alt Hacker NewsTo me there's a very distinct difference between unobtrusive same-service tasteful trailers and entirely unrelated third party ads.
I genuinely discovered great series and films that I enjoyed a lot but I would not have watched otherwise (e.g Shrinking).
This is true for cinema as well.
While I agree that third party advertising is not the same as playing trailers from other same platform shows, once you are in the app, these highly promoted shows are really hard to miss, regardless of how many trailers are placed at the beginning of another show.
For Shrinking, for instance, they placed an almost full screen, auto play trailer in the main carousel. It is also first in the top ten shows, and it appears in a number of other lists.
Regardless of all this, they do play unrelated promotions for their add ons like some sports stuff or the Peacock deal.
